These two <a HREF="http://modis.gsfc.nasa.gov" target="outlink">Moderate Resolution Imaging Spectroradiometer</a> (MODIS) images of the eastern United States captured on by first the <a HREF="http://terra.nasa.gov/" target="outlink">Terra</a> and then the <a HREF="http://aqua.nasa.gov" target="outlink">Aqua</a> satellite on successive days show autumn burnishing the Appalachian Mountains with its copper touch. On September 23, a winter storm hovers at the north of the image and dips into West Virginia. By the next day, the clouds were gone and a dusting of snow remained on the Allegheny Mountains in the eastern part of the state. A long, green valley known as the Shenandoah Valley stretches out to the east of the Alleghenies, all the way from Pennsylvania down into Georgia. A few scattered fires were detected by MODIS and are marked with red dots. Sensor: Aqua/MODIS. Data Start Date: 11/24/02. Data End Date: 11/24/02.
